From b8925b7c2f867df6ce3e20deb4b3e2b9b32b20ff Mon Sep 17 00:00:00 2001

Subject: [PATCH 48/54] ARM: dts: rockchip: Split GPIO keys for veyron into
 multiple devices

With a single device DT overrides can become messy, especially when
keys are added or removed. Multiple devices also allow to
enable/disable wakeup per key/group.

[used actual switch+event constants in new lid-switch entry]
